On “Richard III” nights, he has to stay focused since he doesn’t come onstage until Act 5. During the downtime, he has to gear up to deliver several long speeches directly to members of the audience, whom he can see “very clearly.”

For “Inherit the Wind,” Amboyer tries to connect and banter with cast mates to bring out his positive energy, since his character “has to have a likable energy that makes the audience want to root for him.”

Amboyer said he hasn’t had any mix-ups to date.

“Because of all the preparation that goes into one performance, I haven’t yet confused who I am, or what play I’m about to do,” he said. “My daily routine leading up to curtain is very much planned out. It might be interesting, however, to try and surprise myself and show up to the theater at the last minute and say, ‘So who am I today, guys?’ It could completely derail my performance, or maybe the adrenaline would kick in and I’d learn something new.

“But when 600-something people each night are coming to support and enjoy our plays, I feel a great responsibility to do whatever I can to consistently deliver my best possible performance every night.”
